LINEAR BEARINGS AND SHAFT

HRC 65 Precision Hardened Shaft – Premium Linear Motion & Industrial Grade Steel Rod

Experience exceptional durability, accuracy, and performance with our HRC 65 precision-ground shaft, engineered for high-demand industrial and mechanical applications. Manufactured from high-carbon chromium bearing steel (AISI 52100 or equivalent), each shaft undergoes a rigorous heat treatment process to achieve a uniform hardness of HRC 65 ±1 on the Rockwell scale — ensuring outstanding strength and long-lasting wear resistance.

Key Features

• High Surface Hardness:
  With a surface hardness of HRC 65, this shaft provides superior resistance to abrasion, deformation, and fatigue even under heavy loads and continuous operation.

• Precision Ground & Polished Finish:
  The surface is finely ground to achieve a roughness value of Ra ≤ 0.2 μm, guaranteeing ultra-smooth linear motion, minimal vibration, and quiet operation.

• Excellent Dimensional Accuracy:
  Every shaft is straightened to a tolerance of ≤ 0.02 mm per 300 mm, ensuring perfect alignment and reliability for linear bearings, pillow blocks, and motion systems.

• High Tensile Strength:
  Tensile strength of approximately 2,000–2,200 MPa allows it to withstand intense operational stress without bending or distortion.

• Heat Treated & Stress Relieved:
  Fully hardened through heat treatment and stabilized to maintain strength across the entire cross-section, providing both surface and core durability.

• Corrosion Protection:
  Optional chrome plating or black oxide coating adds protection against moisture, oxidation, and industrial environments.

Applications

Perfectly suited for:

• Linear motion guides and bearing systems

• CNC machinery and automation equipment

• Robotics and precision engineering assemblies

• Conveyor systems and motion platforms

• Heavy-duty industrial machines requiring extreme durability
